摘要 根据中国西南峨眉山玄武岩一粗面岩系和同源的白马基性超基性岩体的地球化学研究发现:(1)对于分离结晶成因的岩浆岩,元素丰度互呈幂函数关系。报导了这一定律的事实依据,引证了安底斯山脉玄武岩—流纹岩系元素含量数据的系统证实实例。(2)指出:对同源同结晶阶段岩浆岩,元素含量关系有7种基本型式并遵守同一关系式。同源同结晶阶段岩浆岩元素丰度关系式是讨论同源不同结晶阶段岩浆岩元素丰度关系的基础。 Based on the geochemical study of the Emeishan basalt - trachyte series (southwest of China) and the adjacent Beima mafic and ultramafic layered intrusion, the authors discover that the elemental abundances possess a power function relationship with each other for igneous rock formed by fractional crystallization of a magma; report the data bases of this law and confirm the law from the data of recent volcanism in southern Andes, Chile and layer intrusion of Kiglapait, Canada; then, the authors point out that there in two igneous rocks formed from the same parent magma at the same crystallization stage are 7 essential patterns of concentration relationship between two elements; and all of the 7 patterns obey the same equation of the elemental abundance relationship. The equations of the elemental abundance relationship in igneous rocks formed from the same parent magma at the same crystallization stage are the bases on which we could discuss the problems of the multistage fractional crystallization of magma.
